thanks mate.Why not try smartdevil hydrogel sp? It's on taobao. I used it and it's pretty good. Smoother than the original SP. Check back a few threads for the link I shared.
i dunch have taobao account... and, I suck at pasting SPs. can imagine myself wasting resources if I diy.
would local shops happen to have the same SP? I would pay for their service...
